Question

if radii of two circular cylinders are in the ratio 3 is to4 and their heights are in the ratio 4 is to
5 find the ratios of curved surfaces
​

Answer 1

Answer:

plz mark me as brainliest

Step-by-step explanation:

The radii of two cylinders are in ratio 4:3

Their heights are in the ratio 4:5

Let the ratio be x.

So radii are 4x and 3x

Heights are 4x and 5x

Formula of curved surface area of cylinder=2$\pi$rh

ratios of curved surfaces = 4*3/4*5

=3:5
